Types

type Balance 

type Balance struct {
	Address common.Address
	Amount  *big.Int
}

Balance represents a single Ethereum addresses Ether balance

type BlockchainLifecycle 

type BlockchainLifecycle struct {
	// contains filtered or unexported fields
}

BlockchainLifecycle is a testing utility for taking snapshots of the blockchain state on Ganache and reverting those snapshots at a later point in time. Ganache supports performing multiple snapshots that can then be reverted in LIFO order.

func NewBlockchainLifecycle 

func NewBlockchainLifecycle(rpcURL string) (*BlockchainLifecycle, error)

NewBlockchainLifecycle instantiates a new blockchainLifecycle instance

func (*BlockchainLifecycle) Revert 

func (b *BlockchainLifecycle) Revert(t *testing.T)

Revert reverts the latest snapshot of blockchain state created

func (*BlockchainLifecycle) Start 

func (b *BlockchainLifecycle) Start(t *testing.T)

Start creates a snapshot of the blockchain state at that point in time and adds it's snapshotId to a stack

type ContractAddresses 

type ContractAddresses struct {
	ERC20Proxy           common.Address
	ERC721Proxy          common.Address
	OrderValidationUtils common.Address
	Exchange             common.Address
	EthBalanceChecker    common.Address
	Coordinator          common.Address
	CoordinatorRegistry  common.Address
}

ContractAddresses maps a contract's name to it's Ethereum address

func GetContractAddressesForNetworkID 

func GetContractAddressesForNetworkID(networkID int) (ContractAddresses, error)

GetContractAddressesForNetworkID returns the contract name mapping for the given network. It returns an error if the network doesn't exist.

type ECSignature 

type ECSignature struct {
	V byte
	R common.Hash
	S common.Hash
}

ECSignature contains the parameters of an elliptic curve signature

type ETHWatcher 

type ETHWatcher struct {
	// contains filtered or unexported fields
}

ETHWatcher allows for watching a set of Ethereum addresses for ETH balance changes

func NewETHWatcher 

func NewETHWatcher(minPollingInterval time.Duration, ethClient *ethclient.Client, networkID int) (*ETHWatcher, error)

NewETHWatcher creates a new instance of ETHWatcher

func (*ETHWatcher) Add 

func (e *ETHWatcher) Add(addresses []common.Address) (addressToBalance map[common.Address]*big.Int, failedAddresses []common.Address)

Add adds new Ethereum addresses we'd like to track for balance changes and returns a map of added address to balance, and an array of addresses that it failed to add due to failed network requests

func (*ETHWatcher) GetBalance 

func (e *ETHWatcher) GetBalance(address common.Address) (*big.Int, error)

GetBalance returns the Ether balance for a particular Ethereum address

func (*ETHWatcher) Receive 

func (e *ETHWatcher) Receive() <-chan Balance

Receive returns a read-only channel that can be used to listen for modified ETH balances

func (*ETHWatcher) Remove 

func (e *ETHWatcher) Remove(address common.Address)

Remove removes a new Ethereum address we no longer want to track for balance changes

func (*ETHWatcher) Start 

func (e *ETHWatcher) Start() error

Start begins the ETH balance poller

func (*ETHWatcher) Stop 

func (e *ETHWatcher) Stop()

Stop stops the ETH balance poller

type EthRPCSigner 

type EthRPCSigner struct {
	// contains filtered or unexported fields
}

EthRPCSigner is a signer that uses a call to Ethereum JSON-RPC method `eth_call` to produce a signature

func (*EthRPCSigner) EthSign 

func (e *EthRPCSigner) EthSign(message []byte, signerAddress common.Address) (*ECSignature, error)

EthSign signs a message via the `eth_sign` Ethereum JSON-RPC call

type LocalSigner 

type LocalSigner struct {
	// contains filtered or unexported fields
}

LocalSigner is a signer that produces an `eth_sign`-compatible signature locally using a private key

func (*LocalSigner) EthSign 

func (l *LocalSigner) EthSign(message []byte, signerAddress common.Address) (*ECSignature, error)

EthSign mimicks the signing of `eth_sign` locally its supplied private key

func (*LocalSigner) GetSignerAddress 

func (l *LocalSigner) GetSignerAddress() common.Address

GetSignerAddress returns the signerAddress corresponding to LocalSigner's private key

type Signer 

type Signer interface {
	EthSign(message []byte, signerAddress common.Address) (*ECSignature, error)
}

Signer defines the methods needed to act as a elliptic curve signer

func NewEthRPCSigner 

func NewEthRPCSigner(rpcClient *rpc.Client) Signer

NewEthRPCSigner instantiates a new EthRPCSigner

func NewLocalSigner 

func NewLocalSigner(privateKey *ecdsa.PrivateKey) Signer

NewLocalSigner instantiates a new LocalSigner

func NewTestSigner 

func NewTestSigner() Signer

NewTestSigner instantiates a new LocalSigner

type TestSigner 

type TestSigner struct{}

TestSigner generates `eth_sign` signatures for test accounts available on the test Ethereum node Ganache

func (*TestSigner) EthSign 

func (t *TestSigner) EthSign(message []byte, signerAddress common.Address) (*ECSignature, error)

EthSign generates an `eth_sign` equivalent signature using an public/private key pair hard-coded in the constants package.

func (*TestSigner) SignTx 

func (t *TestSigner) SignTx(message []byte, signerAddress common.Address) ([]byte, error)

SignTx signs an Ethereum transaction with a public/private key pair hard-coded in the constants package. It returns the transaction signature.
